WHEEDPLOW.

SPECIFICATION forming part of Letters Patent No. 396,605, dated January 22, 1889.

Application filed October 2,1888. Serial No. 286,949, (No model.)

To all whom it may concer/zr:

Be it known that LHANs H. SATER, a citi- Zen of the United States, residing at Dubuque, in the county of Dubuque and State of Iowa, have invented certain new and useful lmprovements in Wheel-Flows; and Ido hereby declare the following to be a full, clear, and eXact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to Various new and useful improvements in wheel-plows, particularlyto means for elevating and depressing the plow and plow-beam, so that these parts will always be balanced on the supportingwheels, whether the furrow-wheel is below or in advance of the land-wheel, or whether both wheels are in the same plane.

My invention accordingly consists of a peculiarly-constructed axle to which the plow beam is pivoted, and which acts in conjunction with a cam and a connecting-rod, and also with other mechanism, so that when the operating-lever is elevated the land-wheel is forced back and upwardly, the furrow-wheel is advanced, and the plow is lowered, so that the point enters the ground, and when the operating-lever is depressed the furrow and lan d wheels are brought back in the same plane and the plow is elevated, the various parts acting together in such a way that `whether the plow is elevated or lowered in action or not it will always be nearly perfectly balanced on the supporting-wheels.

My invention also relates to a novel device acting in conjunction with the plow-beam, so that when in -use and any small obstructions-such as stones, dac-are encountered the plow will not partake of that oscillating jerky motion noticed in the plows heretofore used under similar circumstances, but will always remain perfectly steady; and the obj ects of my invention are to produce a plow composed of but comparatively few parts, one durable in use, effect-ive in operation, and one in which the plow is always nearly balanced on the supporting-wheels, thus obviating any unnecessary strain. l attain these objects by the use of mechanism illustrated in the accompanying drawings, wherein like parts vare represented by identical letters of reference in ,each view, and in which- Figure l a perspective view of the entire device, showing the plow as being elevated; Fig. 2, a similar' view showing the plow as be ing lowered; Fig. 3, a front elevation of the same; Fig. ll, an elevation of the locking-segment andsupport for the operating-lever.

In the above views A represents the landwheel-that is, the wheel which rides on the unplowed portion-and B the furrow-wheel. Both of these wheels are preferably the same size and may be of any well-known. construction; but l prefer to `make thementirely of metal, so as to insure great strength with but little weight. These wheels are mounted on an axle, (l, of peculiar construction, made preferably of metal. This axle C is composed of the spindle or skein a for thc furrow-wheel, the long inclined portion b, the arched portion c, supporting the plow and plow-beams, the curved portion d, and the spindle e in a horizontal plane somewhat above the spindle a. Eneircling this spindle e is the cylindrical portion f of the swinging arm D, made of metal and provided at its lower end with the spindle or skein g, on which the land-wheel A rotates.

Suitable nuts, /L h lz, or other fastening devices, are attached to the ends' of the spindles or skeins d, e, and g, to prevent the furrowwheel B, swinging arm D, and land-wheel A, respectively, from becoming disengaged from said spindles. At the eXtreme upper part of the arch portion c a bearing, t, is formed, for the purpose hereinafter explained.

Directly beneath the bearing t and the bracing-rod j the plow-beam E, supporting the plow F, is pivoted. The bearing .at this point may be of any well-known construction; but I prefer to make use of the two cone-shaped pieces k 7c', attached to each side of the plowbeam by means 'of nut and bolts k2 k3, and passing through the lower portion of said arch c, and provided on their ends with nuts 7a4, for the purpose of holding said cone-shaped portions securely in position. Instead of having the cone-shaped portions 7c 71; extending entirely through said arched portion c, they may extend only to the same, and in this case a bolt is passed through the inside of both of said cone-shaped portions, through the plowbeam, and through the arch, being provided on its outer end with suitable nuts. By the IOO use of either of these two pivoting devices it will be seen that the plow-beam and plow may be oscillated, pendulum-like, beneath said arch.

At the curved portion G ot' the plow-beam E is pivoted a lockiilg-scgment, ll,made pret'- erably of metal, as is, indeed, most all the parts of the plow. This locking segment li is composed of the two vertical. arms L I, both being attached to one side of the plow-beain, a bearing portion, in, at the top of the arm Z, a horizontal arm, m', connecting the bearing portion m of the arm l with the upper end of the arm l and extending ont some distance beyond the latter, an arm, n, extending' obliquely up from said bearing portion fm., and a curved rack, a, connecting the outer ends of the arms m and n. On the other side olf the plowbeam, directly opposite the locking-segment H, is a supporting-bracket I, composed of the vertical arm o, of the exact length of the arm I, and provided at its upper end with the bearing o on an exact line with the bearing portion on, and an oblique arm, p, extending down from said bearing o and attached to the plow-beam. Pivoted on a horizontal bolt, q, extending from the bearing in. to the bearing o', is a lever, J, provided with a perpendicular shorter arm, K. This lever J is provided with a lug, q', extendingl over the curved rack n', and with a spring-latch, q, of any well-known construction, engaging with the teeth of said rack, A wire or rod, o, connects the said latch with the small handlever r', located near the upper end of the lever J, and by means oil which the said latch maybe operated and withdrawn from the end of said lever.

Connecting the bearing with the lower end of the arm K ot the lever J is a rod, L, provided at its forward end with an enlarged portion, s, having a semicireular opening therein engaging under said bearing/i, and with a locking-block, s', also provided with a semicireular opening' therein engaging over said bearing-piece yi and attached to said connecting-rod L by means of bolts and nuts, as shown. this means it will be seen that the connecting-rod L may be disengaged `from the bearing 'i by simply removing thc locking-block s.

On the swinging arm. l) a cam, M, is secured, made substantially of the form shown, and provided along' its outer edge with a series of openings or holes, t 15 t. A connectingrod, N, is provided with a circular lug, t', thereon adapted to be inserted in one of said openings or holes t 15 t, and'on the outside of said circular lug t a split pin, t, is adapted to be introduced for the purpose of locking said lug securely in place. The other end of this rod N is preferably attached to the bolt u.,

which lholds the lower end of the oblique arm p in position on the plow-beam. At a point on said rod N, near the point of connection with said bolt u, a rigid arm, O, extends nearly vertically upward for some distance,

and is provided on its rear edge with a series oi' notches, t' fr, in one of which the link o of the spring P engages. rlhe other end of this spring P is provided with another lilik, o, encircling the cone-shaped piece 7i: and tending to exert a constant pressure of the vertical arm O toward the arch c.

On the extreme lower portion of the axle (i, directly above the spindle e, is a lugor projection, w, and on the cylindrical portion j' ot' the swinging arm l) is a similar projection, it, so that when said swinging arm is directly vertical these two projections abut against each other, and said swinging arm is prevented i'roin any further movement toward the front of the plow.

By means of the openings or holes t t t t in the cam M the length of the rod N from the plow-beam can be conveniently adjusted and the elevation oi' the land-wheel thereby easily regulated.

The operation ot the whole device, supposing the plow and plow-beams to be elevated, is as follows: The small handsleverfi" is first forced backward, carrying the connecting rod or wire r with it and disengaging the latch q from the rack n of the locking-segment H. The operating-lever J is now elevated and carries the arm K in substantially a horiZontal direction. The connecting-rod L, being' attached to said arm K, moves therewith and forces the upper part of the arch c backwardly, which turns as on a pivot and on the conical pieces it' k. The lower end of the axle will of course be forced in an opposite directionthat is, toward the front of the plow and carries the spindles or skeins a and e with them and the furrow-wheel B. The land-wheel will not be advanced, but, on the contrary, will be elevated and forced backward, by'reason o't the rod N opposin the forward motion of the spindle or skein e. It will now be seen that the elevation of the wheels A and B is practically the same as a depression of the plow, which is at liberty to enter the ground, and it will also be seen that the elevation of the land-wheel will place this wheel in a higher plane than the furrow-wheel, as has been always done; but that the motion forward o'i' the furrow-wheel and the mot-ion backward of the land-wheel are practically equal, so that the plow will be nearlybalanced under the arch c, whether in ground or out.

lYlien the plow is to be elevated, the operating-lever J is depressed, all the motions just described being reversed, and the two wheels A and B are brought forward and back, so as to be in the saine horizontal and vertical plane. lV hen the swinging' arm B is thus vertical, the two lugs w to abut against each other and any further motion of the arm is prevented.

lV hen the plow is in use, should either wheel come into contact with any obstructi on-io r in stance, a stone-without the spring P, and the arch c, the plow and beam might be gin to oscillate; but by means of this spring TOO IIO

any sueh motion is prevented by reason of the Constant tendency of the spring to torce this aroh baekwardly.

Man)Y of the parte above described maxv be varied somewhat in torni; but such changes would require merely the exereiee of mechanieal skill, and not the application of' inventive ingenuity.

Having' now described my invention, what l elairn as new therein, and desire to Secure by Letters Patent, is-
